Abstract: Prokaryotic expression vector pET-CH of Arabidopsis pumila chitinase gene cDNA was constructed by means of recombinant gene technology and expressed in Escherichia coil BL21 under induction of IPTG, the expressed products were detected by SDS-PAGE analysis.Result show: Recombinant chitinase was efficiently expressed in E. coli BL21, it molecular weight was about 40 KD.The successful construction of prokaryotic expression vector containing Arabidopsis pumila chitinase gene and effective expression of recombinant chitinase in E. coli BL21 laid the foundation for further study on its biological function.

Key words: Arabidopsis pumila, chitinase, cDNA cloning vectors, gene expression
